IMPROVEMENT IN MACHINES CUTTING IRREGULAR FORMS.

Specification forming part of Letters Patent No. 15S,793,"dated Jaruary 19, 1875; applicatior filed October 2, 1874. i

To all whom it may concern: ent jaws at each corner riding on the ways a- Be it known that I, GEORGE A. HALEY, of A guard-Wheel, I), mounted under the out- Ohicago, in the county of Cook and State of wardly-bent end of a brace at each corner of Illinois, have invented an Improvement in the table, runs under the flange a, and serves Machines for Outting Irregular Forms, of not only to guide the table, but also prevents which the following is a specification: it from being lifted off the ways, as shown in The nature of this invention relates to ma- Figs. 5 and 6. A stirrup, F is bolted to the chine for planing grooves and moldings of irunder side of the table, with a step, c, at the regular outline in mantels and other objects middle, in which is stepped a vertical shaft, of marble, which are mounted on a revolving G, on the upper end of which a bevel-gear, 1, bed under a pendent planer-tool, which bed is keyed. The cam-plate H is bolted to the has a reciprocating movement on the Ways of table. The periphery of the cam H is a pendthe frame, while the tool-holder is automaticent flange, internally toothed, as at d. Inside ally turned on its axis, so as to present at all the flange a groove, 0, is cut in the under surtimes the face of the tool to the advancing face of the said cam-plate, as seen in Fig. 10. work. The top end of the shaft D runs in this groove, The invention consists in the novel and whilethe spur-pinion D meshes with the gear peculiar construction and arrangement of the clof the said cam,which is rotated, and through various parts, as more fully hereinafter set it the shaft G and its attachments, by said forth. pinion D while the groove in said cam slides Figure 1, Sheet 1, is a perspective view of the table and its attachments back andforth. the machine. Fig. 2 is an elevation of one- The mantle-front to be grooved is secured to half of a mantel-face, showing the groove the top of the cam-plate. J is a shaft, jourplaned in it by the machine, Fig. 3, Sheet 2, naled through a bearing in the end of the bed, is a plan of the cross-head and top-girt with while its inner end is journaled in the lower the upper cam removed. Fig. 4 is a plan of part of the step 0, and confined by a pin and the table and bed, the lower cam being recollar, so that said shaft will slide with the moved. Fig. 5 is a cross-section. Fig. 6 is a table. K is an oval eccentric gear, whose hub side elevation of one of the corner legs of the is the bearing for the shaft J, on which it is table, showing the arrangement-of the supfeathered. The hub is journaled in a box, f, porting and guiding rollers. Fig.7 is a longiat the end of the frame-bed. K is an oval tudinal section of one of the cam-wheels and eccentric pinion, in like manner journaled in its shaft. Fig. 8 is a sectional side elevation the overhanging standard A Through its of the same. Fig. 9, Sheet 3, is a cross-section hub is'inserted a counter-shaft, J, splined on of the machine. Fig. 10 is a bottom plan of a projecting feather in the eye of the hub. L the lower cam. 5 is a cross-head, gibbed on the gi'rt A adjust- In the drawing, A represents the main frame ed thereon by a traverse screw, 9, threaded in or bed of the machine, provided with longia nut at the back of said cross-head. M is a tudinal ways ac, like an iron-planer, and a tool-holder, like that of an ordinary iron flange, a, Figs. 5, 6, and 9, outside each way. planer, carrying a pendent tool, h. The tool- The frame A is carried up at each end 011 the holder is gibbed on a head, M, and is fed up or back side, forming an overhanging standard, down the face thereof by a feed-screw, i. A A the two being united by a horizontal girt, lug, at the back, upper, and lower end of the A B is the drivingshaft, longitudinally head, is pinned on a vertical shaft, j, passing journaled in bearings at one end of the bed, and journaled through bracket-lugs Z0, secured with a bevel-gear, O, at the inner end thereof, to the face of the cross-head, and which shaft meshing with a bevel-pinion, G, keyed on the j has a pinion, Z, keyed to its upper end. The pendent end of a vertical shaft, D, journaled screw 2' extends up through this pinion, and in a transverse girt, D Near its top is a has a hand-crank at the top to rotate it. N is spur-pinion, D u E is a table, with a doublea shaft, vertically journaled in brackets m, flanged roller, b, journaled in a pair of pendprojecting from the face of the cross-head.

At its top is a bevel-pinion, O, meshing with and receiving motion from a bevel-gear, O, on the inner end of the shaft J. The hub of the pinion O is journaled in a bracket, 11., projecting from the face of the cross-head. P is a cam-plate, secured to the top of the shaft N, and has a groove, 0. cut in its under surface at the periphery. Q is a vertical rock-shaft, journaled inbrackets p, projecting from the face of the cross-head, and to its top is keyed a geared segment, R, having a lateral projecting arm, R, on which there is journaled a friction-roller, r, on a stud, which projects into the groove 0 of the upper cam-plate, while the segment-gear meshes with the pinion l, the office of which is to turn the tool holder and head on their hearing so as always to present the face of the tool to the advance of the work squarely across the plane of the out.

For turning the tool at difficult points, such as at a square corner, or in rounding a short curve, the eccentric gears are necessary in order to give the upper cam a quickenough motion.

The upper cam-plate may be made reversible, for right and left mantle-faces, by forming a groove upon both faces. The lower camplate requires to he made with right and left shapes, or two of them are required for each style of mantle made.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The tool holder M, as described and shown, oscillating on an upright spindle, y, and operated by a grooved cam, P, so as to be always at right angles with the out, as and for the purpose set forth.

2. The combination of the table E, supporting the cam-plate H, and reciprocating upon the ways a of the guard-wheels b on the corners of said table, and flanges a of the frame I GEORGE HALEY.
